Permanent, broadband antireflection coating for infrared window

摘要

infrarotdurchl & auml; local fensterstruktur witha window (10) from a semiconductor material, based ona wellenl & auml; ngenbereichfrom 3 to 12 & mgr; m arefractive index between 2.9 and 3.5 points, and a ultraharten,broadband antireflexionsbeschichtung, comprehensive & ndash; a firstbeschichtungslage (12) of silicon or germanium, & ndash; a firstdiamond like carbon layer (16) on the first beschichtungslage(12), and a ndash;second beschichtungslage (18) from a semiconductor material, thebased on a wellenl & auml; ngenbereichfrom 3 to 12 & mgr; ma refractive index between 2.7 and 4.0 is the firstdiamantartigen carbon layer (16), and a second ndash;diamond like carbon layer (20) on the second beschichtungslage(18).
